- CURTAIN-BOD.

To all whom it mayconcem:

Be it known that L'Cnennus citizen of the United States, residing at Sturgis, in the countyof St. Joseph and State of Michigan, have invented certain new and useful Improvements in "Curtain- Rods; and-I do hereby'declare the following to be a full, cleanand'exaot description of 7 the invention, such as will enable others skilled in the art to which it appertains t0 make and use the same.

' My invention relates to improvements in curtain rods, the object being to provide a sectional rod, the parts of which. shall be adapted for association in various relations to produce rods-of-greatly varying length.

A further-objectyof myinven'tion is to provide a system by'ineans of which a dealer in curtain rods shall beable to provide rods of any length desired, without necessity of cutting, and by the use of a minimum number of parts of 'difiering shapes or dimensions. A further object ofmy-invention is to. providea sectional curtain rod having several combinations and arrangements of structures telescopicallyinterfitting parts and adapted to be locked at the several joints by means 0f wedging or locking devices of uniform di- .mensions.' I I A further obj ect of my invention is to provide simple coupling means for a two-piece telescopically. adjustable curtain rod by means of which the rod can'be lengthened beyond its normal length.

' My invention consists in a curtain rod having twoend members which are adapted to be telescopically connected together, a coupling member adapted to telescopically receive each of the end members, and means for locking the coupling member to the end members.

My invention also consists in a tubular coupling member for curtain rods in combi-' nationv with. longitudinal members of similar cross-section which are adapted to'be telescopically j oined, the coupling member being adapted to be interposedbetween the other membersand formed for telescopic connection with each and the several telescopic joints being adapted'to be locked by locking devices of uniform dimensions;

My invention also consists in the severe.

and parts and in the features of constructain the above and other objects, all as hereinafter described and claimed.

I In the modern development of manufacturing and marketing devices of'this char acter, much has been accomplished in the way of reducing the manufacturing, operations to a minimum, reducing the possible waste of material, and in the simplification up of a number of the of operations and methods of producing articles of the diiferent dimensions required which shall require a minimum stock to be carried by the dealer.

In the curtain rod business, the usual variations in lengths required are from twentyfive inches to forty inches, and two-piece telescopically extensible rods are produced which may be termed the standard or stock size suitable to fill such demands. It goes without question that if such rods are made in very large quantities the manufacturing costcan be reduced. My system contemplates the use of such standard length rods which constitute the vast majority of rods used, as a base, and by means of such stand ard rods, and my improved couplers, which can be made of uniform length or of difi'er-i ent lengths, as desired, producing rods of any greater length which may be called for or needed.

ard length couplers, and by the use of one or more in combination with a standard length rod produce a rod of any length desired, but it should be understood that by means of different length couplers used with rods of shorter than the desired length, the dealer can produce any length of rod called for. i

As illustrated in the drawings my improved sectional rod comprises two formed end members A and B. In section, as shown in Fig. -5-, these members are each chan nel shape having inturned overlapping flanges G, and the various sections of the rod are formed for interfitting telescopic engagement. The outer ends D of the two sections may be formed in any suitable manner for hanging or supporting the rod for instance like that shown wherein the ends D are bent at right angles to the bodies of the end members and are adapted to be hung on suitable supporting brackets E.

I usually make the body portions F and G of the end. members to constitute these two members a curtain rod capable of being extended to forty inches or to that length which constitutes the longer length of the most usual sizes, the two ends F and G being formed for -telescopic engagement with each other as shown in Fig. 2-, that is, the end F telescopically fits .within the end G.

For building up rods longer than the standard or ordinary length, I provide telescopic couplers H, one end J of which is of dimensions to telescopically fit over the connecting end F of the smaller end section A and the other end K of which is formed small enough to fit within the connecting end G of the larger end member B. In other words, the large end J of the houpling member is the same size as the end G of the end member B and fits upon the opposite end member A in the same manner, and likewise the small end K of the coupling member is the same size as the connecting end F of the end member A.

A. stated hereinbefore I prefer to make the coupling members H of uniform length using any number of them which may be necessary in combination with the standard end members A and B to produce the length of rod desired. Fig. 8- illustrates a rod composed" of the end members A and B and a plurality of the coupling members H.

On the other hand, for some purposes, it is advantageous to make the coupling members H of different lengths so that but one thereof shall be necessary in combination with the standard end members A and B for the production of a rod of thedesired length, as illustrated in Fig. 1-. 9-

For locking the several telescopic members together in their adjusted positions I may use the oval locking washer L, as illustrated, or I may crimp the overlapping edges C of the members, as shown in Figs. 6 and 7. My method of building up the rods with the couplers provides that the inside members at each joint which receive the locking washers are uniform in cross-section, and consequently thelocking washers are uniform in dimensions and are thus most cheaply produced. The washers are of a size in one direction to be easily slipped into the rod into the position desired, and are enough larger on another diameter so that when they are forcibly turned to the positions shown in Fig. 3 they expand the inner of the telescopic members against the outer one thereof and thus lrictionally lock the two against relative longitudinal movement.

In some instances I prefer to crimp the overlying edges of the telescopic members as shown in Figs. -6 and 7--, forming these edges inwardly at the same points to provide intcrengaging projections M an recesses N which prevent the rela ive long.

tudinal movement of the two 1ncn-b -r..

These notches or crimps are relatively small, but I make a suflicient numbcr of them to firmly hold the members against longitudina l displacement. I do not herein claim this crimping method of interlocking the telescopic members, the latter forming the sub ect-matter of my co-pending application Ser. No. 111,008, filed July 24, 1916.

I claim as my invention: I

1. A see ional curtain rod comprising two similar til ular end members, one thereof of asize to be telescopically .received within the other, and a coupling member interposed between the two end members fitting telescopically within the larger of said end members at one end and fitting telescopically upon the other end member at its other end, and means for locking thesev= eral members against relative longitudinal movement.

2. A sectional curtain rod comprising two.

similar end. members of channel shaped cross-section'having inturned edgeflanges one thereof adapted to be teleseopicallyreceived within the other, and a coupling member. of similar cross-section adapted at one end to telescopically fit within the larger end member, and at the other end to telebers and telescgpically engaging both thereof, and means or looking the several members against relative longitudinal movement,

54:. A sectional curtain rod comprising two end members of channel shape crosssection having inturned edge flanges, and
